Great for deploying multiple data centers for outages and application performance. While DNS can point a user to a data center, BIG-IP Global Traffic Manager (GTM) can automatically direct users to the closest or best-performing data center based on business policy, geolocation, and volume spikes (both legitimate and attacks). You can realize the full potential of globally dispersed data centers by using BIG-IP GTM on high-performance devices to provide flexible deployment, seamless disaster recovery, and routing based on quality of service or business criteria. BIG-IP GTM also mitigates DNS DDoS attacks, secures DNS infrastructure, reduces DNS latency and delivers advanced F5 DNS Services.

Disaster recovery

When users, whether from IPv4 or IPv6 clients, try to access a data center that is overloaded or unreachable, BIG-IP GTM automatically and seamlessly directs them to a secondary data center. Users aren’t even aware of the switch. They could be accessing a data center at corporate headquarters, in another city, or on another continent. This capability makes BIG-IP GTM especially important for enterprises that need to maintain operations in the event of a natural disaster, power failure, DNS DDoS attack, or any other large-scale service disruption.

Application management

Distributed applications may rely on several web servers, application servers, and databases that work in tandem. BIG-IP GTM automates the process of tracking and managing interdependencies among individual application services, helping you achieve high availability, persistence, and maintenance for these applications. It eliminates the guesswork, errors, and inefficiencies related to manual management, so you have a holistic framework to manage all application services across multiple sites.

DNS security and performance

With a rapid increase in DNS queries, BIG-IP GTM scales dramatically up to 10x by using DNS Express to manage and absorb millions of legitimate and attack queries, easily delivering high-speed DNS query responses and enabling DNS DDoS attack absorbtion and protection. Adminstrators configure BIG-IP GTM to inspect and manipulate DNS requests and reponses using DNS iRules for a fast, customized DNS infrastructure. An IP Anycast integration with BIG-IP GTM redistributes requests to one IP address among all devices based on geolocation, easily managing all DNS query requests. With DNS Caching and Resolving, the number of DNS queries and the latency can be further reduced with caching by having BIG-IP GTM respond immediately to client requests while providing DNS resolving without requiring the use of an upstream DNS resolver.

In the event of cache poisoning of LDNS servers or man-in-the-middle attacks, BIG-IP GTM DNSSEC complete protection delivers a real-time signed query response, ensuring secure information is received and helping you achieve DNSSEC compliance. In addition, DNSSEC Validation on the client-side enables offload of computations to BIG-IP GTM for resolving and superior DNS performance. The BIG-IP system is now certified by ICSA as a network firewall, and BIG-IP GTM with DNS Services protects your DNS infrastructure from attacks with DNS firewall capabilities. For administrators needing DNS Services added to their network topology without global traffic management, a DNS Services add-on for BIG-IP Local Traffic Manager delivers fast DNS customization and management.

Global business criteria management

Global enterprises often have data centers spread throughout the world. So why send a user in Hong Kong to the Dallas data center when there's one in Singapore? BIG-IP GTM uses geolocation-based load balancing to inspect a user's IP address and determine the most efficient data center. The topology could be based on continent, country, ISP, or custom IP subnet level.
